Running files with elevated privileges: SUID or sudo?

["Abel Martín" <abel.martin.ruiz@gmail.com>]

Hi list.

I have to deploy wpasupplicant and wpagui debian packages on a large amount of computers with special predefined config files. wpa_gui has to be executed by unprivileged users. The problem is that wpa_gui needs to be run with elevated privileges to read WPA settings from a socket opened by wpa_supplicant. My question is, which approach do you find better: setting on wpa_gui SUID bit or allowing regular users to run it via sudo without password? Or do you think it is better creating a group, granting execution on wpa_gui for this group and adding users to this group? In any case and for the sake of time I would like to do this modifying the original packages involved or creating a configuration meta-package.

Thanks!
